Application To all whomitmag/ concern.

Be itknown that' I; Bum: L. Worm ole, a

V citizen of theUnitedStates, and aresident p full, clear, and

of Tucson, in the county of Pima and Territory of Arizona, have invented a new and Improved Apparatus forBurning Hydrocarbon Fuels, of which the following is a exact description,

My invention reiates to furnaces such as are employed for smelting and roasting ores, and for heating various media.

y moreparticular object is to introduce finely comimnutcd carbonaceous material into a precmstlng flame, and to supply air or its equivalent at the pointof contact be tween -the connninuted material and the 1 fiame, so as to insure perfect combustion, economy of materials, and a high degree of heat.

Reference is to be had to the accompany ing drawings forming a part-0f this specification, .in which similar characters of reference indicate corresponding parts in both used for feeding showing the auxiliary burner in and also showing the various supply pipes i water the views.

Figure 1 is a vertical section through a sinclting'furnace made in accordance with my invention and showing the mechanism the comminuted. carbonaceous material. and also showing the main burner where this material is brought into contact with air and flame. this view further showing, the auxilnary burner. for producing said ,flame; and

1g. 2 is an enlarged, fragmentary section through one-oi tho mam burners, this View elevation,

for air and the comniinutcd carbonaceous material.

The inner and outer walls of-the stack are shown at 3. 4, and are separatcd by spaces 5 to be filled with water, and pro 1 'vided with a bottom 6, those parts cousin iutlngg a water-jacket. The base of this jacket is shown at 7 and. may consist ofa ring, the parts just mentioned tonether constituting the so-called upper jacket. The lower water-jacket is shown at 8 and is connected directly with the the box 11 and supported therewith upon jacks 10. Intermediate the upper and lower water-jackets is an aperture 12. Twyer pipes i3, is, which may, if desired, be connected with the bustle pipe. lead downwardly to the main burner it. The twycr pipe 14 taps Specification of Letters Patent.

into an annular section '15 inclcsing anonnular air space It? which is continued obliquely downward at 18s) as to conununicate with the aperture 12. i

Both sides of the turnace'are constructed is duplicated upon the opposite side of the furnace.

A burner tuhe is shown iii and is vicled with a combustion chamber batlle 21 is provided with an annul 2 into which projects is upper the burner tube. 'lhe ti yer pipe into a section 24- which is provided with a space 25.

At 96 is shown nected with it is pipe 28,

a combining tube and conan air pipe 2? and an oil A hatlle tZs jis connected with the tiie 'parts with the pipes 27, 28 just mentioned, together constitutinga carbiu'eter adapted to discharge a vapor, and this vapor passes intoen annular lower end of tube 31.. This lower end of the tube 31 is fla red, as indicated in F 2 for the purpose of giving propcr'shapc to the flame to he produced A pipe cornniunicz rics with the space 25 and is connected with an oil burner This burner may he of any c\ n venient form m dis preferably adapted to burn crude oil, Leading into the'pipe 32 is a smaller pipe 34: provided with hand ralre and connected to a spiral conveyor 36. Another small pipe, 37 is connected.

with this spiral conteyer and isprovided' with a hand valve pipe 37 taps into the section 24. and is therefore incom munication with the space A hopper is shown at 39 from itthe conveyor 36 takes the con'uninuted fuel and continuousl v into the pipes 34, 37.

The 'l'nuncr 33 produces a hydrocarbon fiamc which pusscs downwardly through the tube 31. The carburetor discharges a vapor into the annular passage and this passage entirely encircles the enlarged end of the tuhc Ill the vapor is brought into con} tact with the flame and surrounds the some.

he lower and of the tube 30, because of its flaring! shape and ot' the conformity of the adjacent parts. i have found from-expo rionrea tends to give the flame a substan lially conical shape, air being supplied through the twyer pipes 13, 14L Air from the twycr pipe H passes downwa so thatthe mechanism shown discharges it .rdly into fit! ion

I the section 16 and into the furnace through the annular passage 17, and in doing this, it avoids excessive heating of the burner tube 19. Air also passes downwardly through the lawyer-pipe 13 and this air enters the space 25; here it divides, a part go-' ized by the pressure of the air passing through the pipe 32 and tube 31, so that no distortion of the flame is produced by the air currents.

Comminuted carbonaceous fuel being supplied by the hopper 3'9, and passing downward through the pipes 3 37, is discharged into the pipe 32 and also at the top of the section 2 t, thus finding its way through the annular passage 22. vWhile moving from the passage .22 into the burner tube, the comminuted fuel is brought into contact with the hydro-carbon flame and is most elfcctively consumed, producing a high degree of heat.

- The idea is to produce a hydrocarbon flame Cit and to commingle with this flame under the action of an air-blast, the finely divided particles of carliionaceous fuel. The result is that the finely divided carbonaceous fuel is burned a while in suspension, the combustion taking place so rapidly as to be finished before the particles are driven beyond the reach of the flame.
